Add Vista-style drag-and-drop behavior to your web applications.
WebDragDropExtender’s versatile drag-drop technology enables you to create more
powerful web applications with sophisticated Vista tooltip behaviors and styles.
Cursor effects provide an action indicator – for example, displaying as an “X” to
indicate an invalid drop target. Transparent shadows create a persistent view of
the dragged object. Keyboard states provide varied drop behavior – for example,
hit CTRL to copy the dropped object or press the SHIFT key to move it.
Integrate smoothly with other Intersoft components
The highly capable and extensible WebDragDropExtender integrates smoothly with other
Intersoft controls. Implemented as a set of predefined interfaces and base classes,
WebDragDropExtender‘s open-architecture API enables a custom drag-and-drop implementation
with consistent and reliable behaviors. Special design features in the newest release
provide an enhanced level of support for several Intersoft components, such as WebGrid,
WebDesktopManager, and WebNavPane.
Easily add drag-and-drop data validation
When your application requires a more sophisticated post-drop validation of the
dropped object, WebDragDropExtender achieves this through the use of custom objects
in a client-side event handler. Test objects using the GetDataPresent method and
easily determine the type of the dropped object.
Automatic postback mode
WebDragDropExtender supports drag-and-drop event handling at either client or server.
Handle events client-side to perform most tasks, such as adding or changing an HTML
element dynamically. Invoke server-side handling for tasks such as saving modified
data to a database. You can even use Intersoft’s OnTheFlyPostBack technology for
unsurpassed responsiveness and amazing experience.
